4320 steel has high toughness and strength. It contains low carbon content to achieve good welding characteristics.
Applications:
4320 steel is a steel alloy that has casting, machining and welding capability. It is called a low alloy steel, with low carbon content. The carbon amount allows it to be forged, welded and machined. The manganese component allows for better machinability and better hardening properties. The 4320 steel alloys are used in pins, plates, valves and castings etc..
